Question: Question: When was the building where the heads of the major railroads met in 1883 erected? Passage:In 1870, Charles F. Dowd proposed four time zones based on the meridian through Washington, DC for North American railroads. In 1872. he revised his proposal to base it on the Greenwich meridian. Sandford Fleming, a Scottish-born engineer operating in Canada, proposed worldwide Standard Time at a meeting of the Royal Canadian Institute on February 8, 1879. Cleveland Abbe advocated standard time to better coordinate international weather observations and resultant weather forecasts, which had been coordinated using local solar time. In 1879 he recommended four time zones across the contiguous United States, based upon Greenwich Mean Time. The General Time Convention (renamed the American Railway Association in 1891), an organization of US railroads charged with coordinating schedules and operating standards, became increasingly concerned that if the US government adopted a standard time scheme it would be disadvantageous to its member railroads. William F. Allen, the Convention secretary, argued that North American railroads should adopt a five-zone standard, similar to the one in use today, to avoid government action. On October 11, 1883, the heads of the major railroads met in Chicago at the Grand Pacific Hotel and agreed to adopt Allen's proposed system.

Question: Question: When was the Great Fire of London?
 Passage:Bermondsey was historically a rural parish on the outskirts of London until the 17th century when the area began to be developed as a wealthy suburb following the Great Fire of London. By the 19th century, the once affluent parts of Bermondsey had experienced a serious decline, and became the site of notorious slums with the arrival of industrialisation, docks and migrant housing, especially along the riverside. The most notorious of the slums was known as Jacob's Island, with the boundary approximately the confluence of the Thames and subterranean River Neckinger, at St Saviour's Dock across from Shad Thames, to the west, a tidal ditch just west of George Row to the east, and another tidal ditch just north of London Street (now Wolseley Street) to the south. It was a particularly squalid rookery, and described as "The very capital of cholera" and "The Venice of drains" by The Morning Chronicle in 1849.

Question: Question: Was William Shatner alive the year Retropolis Entertainment was founded? Passage:Retropolis Entertainment was founded in April 2002 by Bob Emmer, Garson Foos, and Richard Foos, three principals from Rhino Records, as the company was negotiating with the five majors for distribution. After selling Rhino to Warner Bros., the three set out to launch a new retro pop culture label. The company's first product was Red, White & Rock, a joint release with PBS station WQED that was produced with Warner Strategic Marketing. In August 2002, Retropolis acquired Biograph Records. Other early releases included blues and jazz CDs from the Biograph label, a Fats Domino CD and DVD, and several documentaries (Superstar: The Life And Times of Andy Warhol, What Happened To Kerouac?). Retroplis was renamed Shout! Factory in April 2003. At that time, Shout had signed a press and distribution agreement with Sony Music Entertainment. With the release of Freaks & Geeks in 2004, Shout! hit its stride and shifted towards a reputable and celebrated television on DVD company. That same year, they released a brand-new CD Has Been with actor William Shatner (produced by Ben Folds) and started releasing classic SCTV box sets.
